Doggett goes to prison to find out how Absalom managed to cure the abductees. That's all you need to know about this scene: that Doggett swallowed his doubts and did some investigating, in the hope that he could help out Scully and Mulder. Why? Because he's a nice, decent guy, despite being crazy stubborn and deeply in denial. Write that down: Doggett is a nice guy. We all love Doggett. Doggett will be our touchstone next season when Mulder and Scully are off in the Cayman Islands, bodysurfing and taking tequila shots and playing patty-cake with their strangely complected and preternaturally strong alien baby.

The hospital set is getting a ton of work this season, isn't it? Skinner skulks around the hallway for a moment before he darts into Mulder's darkened room. Krycek is there, waiting for him. They banter. Skinner needs the vaccine. But the price? He has to make sure that Scully doesn't come to term. Skinner blanches. "You're out of your mind," he spits at Krycek. "No, the answer is no." Krycek swallows. "We all have a life in our hands," he says philosophically. "I have yours. You have Mulder's. Scully has her unborn child's. Let's see who's willing to sacrifice." Skinner stares back at him, real hard.

Doggett's lurking in the hallway outside Mulder's room. Krycek waltzes past him. Doggett watches him walk all the way down the hall before he turns to see Skinner standing in Mulder's room. Down the hall, Scully emerges from Billy Miles's room. Got all that?

Skinner stares down at Mulder's lifeless face.

In the hallway, Doggett stops Scully. He has this sad puppy-dog look on his face, which almost makes me think that...no. Never mind. It's impossible. He's just concerned about her as her partner and her friend. Don't say it. Don't even think it. That thought never even ran through my mind. Ahem. Okay, Scully tells Doggett breathlessly that she's discovered that Mulder has been infected with a virus that will transform him into an alien unless she can stop it. She's amazed when Doggett doesn't argue with her about this entire alien thing, and even more amazed when he tells her that Absalom spun the exact same theory for him earlier in the afternoon. "It's all part of some big alien take over of the world," he dryly concludes. Scully puts two and two together and tells Doggett that Absalom's theory explains why she saw two heartbeats on Billy Miles's heart monitor: one belonged to Billy, the other to the alien. Because I'm sure that earthling medical equipment can monitor alien vital statistics. If aliens even have heartbeats. Unless, of course, they're measurable because it's all part of the hybridization process and -- you know what? I'm stopping there. Scully tells Doggett that she's taking Mulder into surgery to stabilize him so that she can administer the vaccine that she told Skinner to procure for her, and thus prevent Mulder from morphing into an alien. Doggett stares after her as she totters off to struggle into her Mommy and Me Scrubs.
